How to calculate the area of the interior walls of the newly decorated house

General interior wall calculation, it includes four middle area and top area. Because of this bedroom he has open windows and doors. So in the total area is the area of windows and doors that need to be subtracted.

So the area of the interior wall is the area of the 4 perimeter walls plus the area of the top wall minus the area. So the walls of the interior are calculated like this.

The overall surface layer of <> is calculated according to the clearance area between the main walls. The area occupied by structures, equipment foundations, indoor railways, trenches, etc., which protrude from the ground, should be deducted. The area occupied by the partition wall and columns, buttresses, chimneys and holes in the attached wall within 0 3 m2 is not deducted.

The opening part of the door opening, empty ring, heating bag, and niche does not increase the area.

Doorway: A long aisle with a roof inside the gate.

Empty Ring: A hole set up for a purpose. For example, the opening part of the garbage well, the gap where the fire extinguisher is placed, etc.

The wall area is the length of each wall in the home multiplied by the height, and then added up, plus the area of the ceiling (the area of the ceiling is the area of the floor of the room), that is, the perimeter multiplied by the height of the room, and the area of the door and window openings of the decoration company is halved.

The area of the wall is currently calculated by multiplying the length by the width.

Then add the area of each location.

At present, the conventional size is not reduced, if it is a relatively large sliding door, the area is halved. The area calculation of the ceiling is unified according to the area.

The simplest reference calculation (in case of imprecise) is: the usable area x3 rounded. For example, for a 120-square-meter high-rise house, the usable area is generally about 100, 100x3=300, which can be simply calculated as the wall area = about 250 square meters.

Because it involves the deduction of doors and windows, veranda and so on.

If you want to calculate so accurately, you can measure the room yourself.

If you have a CAD drawing, the calculation is very easy. If not, then I'd suggest you'd better use the amount of room by room. It is nothing more than the length multiplied by the width to get the area. I wonder what is your purpose in asking this question?

Novices in decoration generally do not understand the decoration, and many details are not noticed, which leads to conflicts with the decoration company. For example, the owner does not know how to calculate the wall decoration area, and the calculation method he understands is inconsistent with the decoration company, and he will feel cheated when he pays later.

1. There is no unified measurement standard for the area of wall decoration

The decoration industry is deep, there is no unified regulatory standard, different decoration companies have different calculation methods, especially some black-hearted decoration companies deliberately did not remind the owner, Shen Wei did not make detailed provisions in the construction contract, and the owner suddenly realized when the later payment was made, but the decoration company did complete the project, and it is difficult to make it clear that it is difficult to hold accountable at this time.

Second, the calculation of wall area is a more conventional method

There are often such cases: it is agreed in advance to wait for the acceptance of the project and pay according to the total amount of the project settlement. By the end of the project, both sides came up with their own project settlement results, only to find that the two sides were far from each other because of their different calculation methods for the wall.

The owner counted the area of the wall, but the renovation company also took the doors and windows into account, and as a result, there was a dispute between the double-wide cover and the party.

Most regular companies, in the calculation of engineering quantity, generally adopt the method of halving the area of door and window openings without counting the area of the heating hood. In other words, when they calculate the wall area, they ignore the wall area occupied by the heating hood, and the door and window openings are calculated by half the area. This calculation method takes into account that the door and window openings increase the construction difficulty of workers, and is the method used by decoration companies more.

3. The area depends on the agreement between the owner and the decoration company

At present, there is no standard for the calculation method of home improvement engineering quantity, which has led to many disputes between consumers and home improvement companies. How to calculate the wall area of your own house can only rely on the owner and the decoration company to determine a calculation method before the start of construction, and then write it clearly in the contract. If it is a reference, you can consider calculating it according to the method of deducting half of the area of doors and windows, and if the home improvement company's ** is lower than the current reference of local home decoration, the decoration company should be allowed to calculate according to the multiple of the actual area.

Home improvement network reminds owners that many decoration companies will deliberately not explain to the owners in terms of more detailed terms, such as how to calculate the wall area, and the owners will take it for granted that they will understand it literally, and disputes will not be avoided in the later stage, so the owners should pay more attention.

The wall area of the renovated new house needs to be calculated according to the actual situation, generally including the blind bucket area of the wall and ceiling of the room, as well as the ground area that needs to be laid. Here's how the wall area is calculated:

1.Calculate a single area: Measure the width and height of the room (excluding doors and windows) and multiply the two numbers to get the area of a single wall. For example, if the width of the room is 3 meters and the height is meters, then the area of a single wall is 3 square meters.

2.Calculate the total wall area: Add up all the individual wall areas of the room to get the total wall area. For example, a 20 square meter room has 4 single-sided wall areas, each of which is a square meter, then the total wall area is 4 square meters.

3.Subtract the area of the door and window: Subtract the total wall area from the area of the door and window to get the area of the wall that needs to be painted or tiled.

For example, if a room has a door and a window, the door area is 2 square meters, and the window area is 1 square meter, then the area of the wall that needs to be painted or tiled is 30-2-1 = 27 square meters.

It should be noted that when calculating the wall area, the height of the wall should also be taken into account, because the higher the wall, the more paint, bricks, etc. need to be grinded. In addition, the area of special parts such as doors, windows, and columns needs to be taken into account on the wall, and the area of these parts needs to be calculated separately and treated accordingly.

To sum up, the calculation of the wall area of the renovated new house involves many aspects, which need to be comprehensively considered and accurately calculated according to the actual situation to ensure the accuracy and efficiency of the first construction.

The items involved in home renovation are broadly divided into:Walls, ceilings, floors, doors, windows and furnitureand so on.

1.Calculate the wall area The decorative materials of the wall (including the column) generally include: paint, stone, wall tiles, wallpaper, soft package, wainscoting, baseboard, etc.

When calculating the area, the calculation method is different depending on the material. The area of paint, wallpaper, upholstery, and wainscoting is calculated by multiplying the length by the height in "square meters".

2.The length is calculated according to the net length of the main wall; Height: Those without wall skirts are counted from the indoor ground to the bottom of the floor slab, and those with wall skirts are counted from the top of the wall skirt to the bottom of the floor slab; There is a suspended ceiling ceiling from the indoor floor(or wall skirt vertices).Add another 20cm to the lower edge of the ceiling.

3.The area occupied by doors and windows should be deducted (1 2), but the baseboard, mirror line, the area of the hole within 0 3 square meters and the area of the junction between the beam head and the wall should not be deducted. When inlaying stone and wall tiles, the area of the actual paving is calculated in "square meters", and the area of the baseboard installed is calculated according to the net perimeter of the interior wall of the house, and the unit is meters.

4.Calculate the top surface area The decorative materials of the ceiling (including beams) generally include paint, suspended ceiling, corner line (decorative corner flower) and lighting ceiling. The area of the ceiling construction is calculated in "square meters" according to the net area between the walls, excluding the area occupied by the partition wall, the columns passing through the ceiling, the buttress and the chimney of the attached wall.

The length of the top corner line is calculated in "meters" based on the net perimeter of the interior wall of the house.

Summary. 1. You can multiply the length and height of each wall, and then add the area of each wall, and subtract the size of doors and windows, which is suitable for square houses. 2. You can also multiply the fixed coefficient of the total area of the house by 3 and the multiple of the area in the house, and when the value is similar to the actual situation, multiply the area of the house and subtract 10, and the number obtained can be calculated according to three times.

To calculate the area of an interior wall, you first measure the length and width of the interior wall, and then multiply the two numbers to get the area of the wall. For example, if the length of the wall is 4 meters and the width is meters, then the area of the wall is 4m x = 10m.

Regardless of the factors of doors and windows, the wall area = squared.

If you consider windows and doors, you can subtract the area of the windows and doors.

Many people are new to the renovation of new houses, so they don't know much about the knowledge of decoration, especially aboutHow to calculate the area of the interior wall of the decorationproblems. SoHow to calculate the area of the interior wall of the decoration？Let's take a look at the formula for calculating the area of the interior wall of the decoration.

1. Estimation and calculation method: the decoration interior wall area is generally estimated by this method, and the indoor construction area or 3 is the estimation of the interior wall area. If the indoor construction area of the mold is 100 square meters, the general** for the owner is 6 yuan to 8 yuan per square meter, so the actual wall area is estimated as:

100 square meters or 100 3=300 square meters.

2. Calculation method of construction area: indoor construction area refers to the original purchase area, under normal circumstances, the actual utilization rate of the house is about 80. In addition, the walls of the kitchen and bathroom are made of tiles and aluminum gussets.

The wall area of these sections is generally about 10 square meters. The area data obtained through the calculation method of the floor area includes the ceiling, which is almost negligible because the ceiling does not have a very large impact on the floor area of the wall coating.

3. Calculation of sleeve area: the actual usable area of the room. This method of calculating the area of the sleeve is very close to the actual measurement method, which is usually the most convenient and reliable method, and it is also the most chosen method for the calculation of the area of the interior wall of the decoration by the renovation engineer.

4. The most accurate practical measurement method: interior wall length x width - the area of doors and windows.

When it comes to renovating a new home, you must understand the renovation knowledge and the price tags. Otherwise, it's easy to get scammed, and then you will waste a lot of money and may not get the positive decoration effect you want.
